On my hour walk to Aldi this morning passed several people, pungent aftershave one and couple of smokers. Nose detected them from fair distance away, moderate wind and I was downwind but still lingering smell having passed them.
Got me to wondering can virus use smell molecules a la surfboard?
Couple of hours googling later, mucho time on hands as for most, and am none the wiser
Can find many references that corona virus is 0.125 microns and I presume that is diameter and that odour molecules are classed as below 0.3 microns. Tobacco smoke particules are listed as a range from 0.01 to 1.0 micron with most in the 0.2 to 0.25 range. Obviously the visibility of the tobacco smoke makes plain it really is there.
I cannot find anything that says categorically virus cannot travel on these apparently larger things in fact there is a complete dearth on info on such matters.
If anyone knows otherwise a link would be great. Nothing leading to David Icke/Alex Jones and the like please.
